DRAWING- FILE nornnn.

Application filed February This invention relatesto holders for sheet fabrics such as drawings, prints, delicate laces etc.-- In United States Patents Nos.

"l,'13 5,310;and 1 ,165,108 granted to me, I have discloseda file case and drawing holder for this-purppse; In a-eo-pending application a Serial No: 88,21 1,ifiled Feb/15,1926, I have headapted to receive the said one edge and.

'toffirm'ly grip the same evenly therealong.

It is another object of my invention to pro-' vide such a holder wherein onefor several. fabrics can be received and firmly gripped merely operating a .key at one end of the holder.

: In the accompanying drawing I have ilvention, but it will be understood that the invention can "be otherwise embodied and that the :drawing is not to be construed as definingor limiting'the scope of the inveneing re i d ew fo t Pu Re'ferring to theiigures'of the drawing: Figure l a front elevation of a frame wherein are s d a Plur'elity'bf h d comprising my present invention.

' Figure 2 1s an enlarged fragmentary View on a carriage2 carried by an overhead track supported on the ceiling of a vault 4;. The frame is provided with end flanges 5 and 6 between which are supported my improved holders 7 in the position shown in Fig. 1. The menstruation and use of the frame is 1 drawing I -partsnow to be described.

lustrated one specific embodiment of my intion, the claims appended to the specification Figurefi is a front end view of the holder. In the drawing, 1 indicates a: frame hung 15,1926; Serial No. 38,215.

fully disclosed in my said co-pending application; improved holder 7 comprises an elongated casing, preferably in the form of :a brass cylinder as illustrated. An opening 8 isformed through one side thereofyone edge of the casing adjacent the opening being bent inwardly to form a curved support 9 and a cooperatinglmember 10 being pivoted to the opposite edge of the opening at 111. Drawings or other sheet fabrics to be held are adapted to bexgripped hetween the member 10 and support 9 as illustrated. I

Three wedglng members 12 are provided with-in the casing for operating the member 10, two of these members being located near the ends of the casing and the other'at the center thereof. Since these three members 70 are. identical, adescript'ion of one willtsuffice; One of suchmembers is shown in longitudinal sectional view in Fig. 4 of the and comprises the cooperating A pair of 'spaced'su-pporting members 13 and let are secured to thecasing by screws 15 A screw 16 extends longitudinally and entirely through the casing," this screw extending looselythrough' the members 13 and being threaded into the members 14. "A plate 17 is mounted in a slot in the'members 13 and 1 1 and has its front edge 18'e-ngaging against the rear of the pivoted member 10. One' portion ofthe rear edge of the plate is notched at 19 to receive the opposite sides of the member 14 and prevent longitudinal movement of the plate. The remaining rear edgeof the plate "-is inclined at 20 in a manner cooperating with a like inclined face on a wedge member 21 slidably mounted in the slotof the member 13 and having a lug 22 engaging in an annular groove 23 in the screw 16; The arrangement is such that ro.-" tation of the screw in one direction moves it, and with it the wedge member 21, longitudinally with respect to the plate 17, and forces the plates'l? outwardly against the pivoted member 10 and-binds the sheet fabrics tight-,

'ly between theimember 10 and the support 9. The screw is preferably provided with a squared end 24 adapted to be engaged by a'key 2.4. i

J The use of. my invention is believed. to he ohvious. Each holder r is adapted to receive and hold several drawings or other sheet fabrics 25. hen desiring to bind a drawing or other fabric in the holder, the screw 16 is rotated in a direction to permit the member 10 to pivot away from the support 9. The edge of the drawing is then inserted into the opening 8 between the member 10 and support 9. The screw 16 is there after rotated by the key 24 to force the mean ber 10 against the support 9 in a manner binding the fabric tl'ierebetween. The several holders 7 are supported in the frame 1 in the manner indicated, the drawings hanging from each holder loosely overlapping the holders therebelow and the drawings su portedby such holders.

he cylinder 7 not only serves as a holder for thedrawings, but also the drawings can be rolled thereon when they are to be carried some distance. The holding of all sheets along the entire edge in the holder is advantageous, inasmuch as smaller sheets are securely held together with wide sheets. My improved means of fastening the drawings in the cylinders is definite and positive and does not depend on a springholding device which applies pressure in sliort'spans.

Having thus described my invention, what I claim is:

1. A sheet fabric holder comprising the combination of anelongated casing having an opening through one side thereof adapt ed to receive sheet fabrics therein, a member extending longitudinally of the opening in the casing and hinged at one of its longi tudinal edges to one edge of the opening and having its other edge arranged to cooperate;

with the other edge of the opening to bind the sheet fabrics therebetween, and means extending through the casing and operated from one end thereof for moving the said member.

2. A sheet fabric holder comprising the combination of an elongated casing having an opening through one side thereof adapted to receive sheet fabrics therein, a member pivotally mounted at one of its longitudinal edges on one edge of the opening and having its other longitudinal edge arranged to cooperate with the other edge of the opening to bind the sheet fabrics therebetweeu, and means engaging the pivoted member at spaced points and extending through the casing and operated from one end thereof for pivotally moving the member.

3. A sheet fabric holder comprising the combination of an elongated casing having an opening through one side thereof adapted to receive sheet fabrics therein, a member pivotally mounted at one of its longitudinal edges on one edge of the opening and having its other longitudinal edge arranged to v cooperate with the other edge of the opening to bind the sheet fabrics therebetween, :1

cooperating therewith-and with the pivoted member to move the-pivoted member about its pivot when the screw is rotated. I

5. A sheet fabric holder comprising the combination ofan elongated casing hav ng an opening through one side thereof adapted to receive sheet fabrics therein, a 1 member movably mounted on one edge of the opening in a manner to cooperate with the other edge to bind the sheet fabrics therebetween, a plurality of wedge members mounted in and relatively spaced along the casing for moving the first-mentioned member, and a unitary means operative from one end of the casing and having spaced wedges for operating all the said wedge members in a manner to move the first member totbind or release fabrics placed in the openin a 6. A sheet fabric holder comprising the combination of an elongated casing having an opening through one side thereof adapted to receive sheet fabrics therein, a clam ing men'iber movably mounted at one edge 0 the opening and arranged to coope1'ateJvitl1 the other edge of the opening to bind the sheet fabrics therebetween, spaced supporting members arranged in pairs and provided with slots, wedge plates mounted in the slots and each interlocked with one of the members of each pair of supporting members, a screw extending longitudinally of the easin g and mounted in the supporting members and having a threaded engagement with said one of thepairs of same and provided with annular grooves and wedge members engaging the wedge plates and having lugs fitting in the groovesof the said screw and movable longitudinally of the casing by the said screw to actuate the wedge plates and 0 erate the movably mounted clamping mem er.

7. A sheet fabric holder comprising the combination of an elongated casing having an opening through one side thereof adapted to receive sheet fabrics therein, a clamping member movably mounted at one edge of the opening and ar 'anged to cooperate with the other edge of the opening to bind the sheet fabrics therebetwecn, spaced support- .ing members arranged in pairs and fixed to the casing and provided with slots, wedge plates mounted in the slots of the support-- ing members and movable transversely of the casing and arranged to engage the clamping member at spaced points, a screw mounted in said supporting members and having a threaded engagement with certain of the supporting members and movable longitudinally of the casing when rotated, and

Wedge members interlocked with the screw and movable longitudinally of the easing with the screw to move the wedge plates outwardly and operate the movably mount-- ed'clamping member.
